I agree completely about not trying to time the market.

Dollar-cost averaging is a good idea.

But if you'd rather invest all of your money at one time, if you are planning on investing in a mutual fund you may want to look at when they distribute their capital gains, so you don't end up getting taxed. For example, on the money coming in at Christmas, you may want to wait until after the first of the year to invest it.
